Bennet has spent $1.9 million on advertising to Romanoff’s roughly $757,000, both campaigns said. Romanoff’s total spending so far is $1.7 million, compared with Bennet’s nearly $5.8 million.

Now, $4,100,000 is not just a lot of money. That’s a LOT of money.

Some perspective: The $4.1 million more Bennet has spent merely to struggle to stay even with Romanoff is $900,000 more than the total Democratic contenders Mike Miles[4] and Ken Salazar[5] spent in 2004 – combined.

Your Spotted This Morning correspondent admits great surprise (even though the reports on the overspending have been piling up for months now, it’s still shocking to see the tally), and wonders whether the erstwhile underdog could maintain his momentum in the general election, should he pull this off.

As the POLITICO’s David Cantainese notes[6], a key Romanoff campaign strategy has been to eschew donations from Political Action Committees. And while the campaign continues to stress that’s the plan, it doesn’t appear as stringent toward some outside assistance as it might have in the past.

The report – if read between the lines – seems to answer a question that’s been vexing some Democrats: Should Romanoff go on to Election Day, it looks like his campaign is prepared to accept the assistance of the Democratic Senatorial Campaign Committee[7].

Cantanese notes that Romanoff told The Colorado Statesman[8] he would not take money from outside groups like the DSCC.

Romanoff’s campaign told POLITICO[9] Monday the Statesman was not correct in its account and no decisions about DSCC funding have yet been made.

“Andrew was talking about outside interference, of all sorts, in the primary. The subject of DSCC money in the general has not arisen. We are focused on Aug. 10,” said spokesman Roy Teicher. “No one is saying, one way or the other, whether Andrew will accept DSCC money. The subject has not come up. Such a discussion, we believe, is premature.”

Indeed. That would be my answer, as well.
